FLUSHING-VALVE.

Specification of Letters Patent.

Patented Aug. 29, 1916.

Application filed April 19, 1915. Serial N o. 22,412.

To all whom z't may concern:

Be it known that I, ALEXANDER FELEKI, subject of the Apostolic King ofHungary, residing at New York, in the county of New York and State ofNew York, have invented certain new and useful Improvements inFlushing-Valves, of which the following is a specification.

This invention relates to ushing valves, and the object of the inventionis to provide a simple and eiiicient device which will be noiseless inits operation and by the use of which the ordinary cistern or tank willbe dispensed with.

The invention is illustrated in the accompanying drawings, and consistsin certain novel features, which will be hereinafter irst fullydescribed and then more particw larly pointed out in the claimsfollowing the detailed description.

In the drawings: Figure 1 is a sectional elevation of a flushing valveembodying my present improvements; Fig. 2 is a section on the line 2-2of Fig. l; and Fig. 3 is an enlarged detail section of the regulatingpiston.

In carrying out my invention, I interpose between the supply pipe 1 andthe flush pipe 2 a casting or coupling by which the said pipes will bedirectly connected. In the present drawings, this coupling is indicatedby the reference numeral 3 and consists of a substantially cylindricalbody having a branch 4 on one side which is coupled directly to thesupply pipe 1 and having a branch 5 on the opposite sidein a higherplane than the branch 4 which is coupled to the flush pipe. In thepresent instance, the elements 2 and 5 are connected by an e1- bow 6.

The upper end of the Coupling 3 is closed by a cap 7 having a hollowcentral stem 8 rising therefrom to form a guide for the piston rod 9,and upon the upper extremity of the said stein or guide is asupplemental cap l0 by which the end of the guide 1s closed around thepiston rod, as will -be readily understood. Said piston rod 9 extendsaxially through the casting 3 and has Secured thereto, at anintermediate point of its length, a valve disk 11 which is adapted toseat upon the annular partition 12 Within the casting immediately abovethe branch 4 which constitutes the inlet of the casting. This valve diskmay, if desired, be covered with leather or other material to torni apacking between the valve and its seat, and 1t will'be readilyunderstood that, when the valve 1s closed or seated, the flow throughthe coupling or casting 3 will becut off and, if the valve be raised oropened, the iiow through the coupling will be permitted.

The lower portion of the casting or coupling 3 is reduced in diameter,as shown at 13, and the lower extremity of this reduced portion isclosed by a cap 111. Upon the lower extremity of the piston rod 9 ismounted a regulating piston which is adapted to retard the descent ofthe piston rod with its attached valve 11 and thereby efect a noiselessseating of the valve. This regulating piston consists, in thearrangement illustrated, of a' disk 15 secured upon the piston rod 9 ata point somewhat above the lower extremity of the same, and of adiameter slightly less than the bore of the reducedv portion 13 of thecoupling. This disk 15 constitutes a stop or fixed abutment for theflexible washer or cup piston 16 which is itted around the lower portionof the piston rod and against the said disk and is clamped to the saiddisk by a metallic or' other rigid washer 17 and a nut 18 mounted on thepiston rod and bearing against the said washer, as clearly shown inFigs. 1 and 3. It will be readily understood that upon the upwardmovement of the piston rod, the piston 16 will yield to theforce offluid above the disk 15 so that the fluid may flow around the pistoninto the lower end ,of the cylinder or coupling. On the return movementof the piston rod, the pressure of the fluid below the piston will causethe same to expand against the walls of the cylinder and, consequently,the descent of the several parts will be resisted so that the seating ofthe valve will be retarded and v will, consequently, be effectedquietly.

It is, of course, obvious that the fluid below the piston must bepermitted to escape or otherwise the piston and the valve would be heldpermanently in a raised position. In the present instance, I provide avent passage 19 which opens at its lower end through the lower end ofthe piston rod and at its upper end through the side of the rod abovethe piston, as shown most clearly in Fig. 3. In the lower end of thevent, I mount a regulating screw 20 which has a tapered groove in oneside and may be set in or out so as to regulate the eiective diameter otthe vent or entirely close the same and thereby easily and eiectuallyregulate the ventingflow.

The upper end of the piston rod 9 is rigid with a vertically disposedrack bar 2l which bears against and is guided by flanged rollers 22disposed above the cylinder, and this rack bar is engaged and operatedby a segmental gear 23. The said segmental gear is formed upon orsecured rigidly to an operating lever 24 which is fulcrumed at one side.

mounted, and the coupling or cylinder 3V may be secured to the saidplate by means of screws or bolts inserted through the lugs or ears 30formed on the cylinder. AA covering or inclosing case 31 may be fittedover the working parts, and this cover will be provided with a slot 32to accommodate the operating lever and will be preferably lined withfelt or some similar material, as indicated at 33, so as to protect theworking parts against variations in temperature.

It is thought the operation of my device will be readily understood fromthe foregoing description taken in connection with the accompanyingdrawings. When it is desired to permit the flow through the iiushingpipe, a pull is exerted upon thejchain 25 which will serve to raise theinner end of the lever 24 against the ,influence of the weight 26. Thismovement of the lever will, of course, impart movement to the segmentalgear 23 which in turn will exert a lifting action upon the rack bar 21so that the piston rod with the valve 11 and the regulating pistonattached thereto will be raised, the valve 1l leaving its seat andthereby permitting flow through the coupling or cylind e'r`3 from thesupply pipe l and the inlet 4, past the valve seat, and thence outthrough the branch or outlet 5 into the flush pipe. The iow may becontinued, of course, as long as the holding force is exerted upon thechain 25, but the instant the said chain is released, the weight 26 willdescend by gravity and cause a return movement of the parts which willbring the valve 11 toward its seat. During the iiushing operation, someliquid will have accumulated below the regulating piston and, when thedescending movement of the piston begins, this liquid willbe subjectedto some pressure which will react upon the piston and the valve to re-'the valve 11, and that the inal seating of the valve will be eiectednoiselessly.

It will be readily noted that the apparatus is composed of very fewparts which are simple in their construction, compact in theirarrangement and are easily operated and also readily accessible shouldit become necessary through accident or otherwise to make repairs.

Having thus described the invention, what is claimed as new is 1. In adevice for the purpose set forth, thecombination of a casing providedwith an inlet and an outlet and an internal valve seat between the inletand the outlet, the lower portion of said casing being reduced, a pistonrod disposed axially in the casing and extending through the upper endthereof, a valve on said rod adapted to engage said valve seat, aretarding'piston on the lower end of said rod playing in the reducedlower portion of the casing, a rack bar rigid with the upper end of thepiston rod, a lever fulcrumed intermediate its ends at one side of thepiston rod, and a segmental gear meshing with the rack bar and fixed tothe lever with its pivot concentric with the fulcrum of the lever, thelever extending beyond the rack bar and being provided at its inner endwith a counterbalance and at its outer end with an operating medium.

2. In a device for the purpose set forth, the combination of a wallplate, a casing secured thereto and having an inlet and an outlet, apiston rod disposed within the casing and extending through the upperend thereof, a valve carried by said rod and seating within the casingbetween the inlet and the outlet, a retarding piston carried by thelower end of said rod and playing in the lower end of the casing, abracket secured to the wall plate above the casing, a lever fulcrumedupon said bracket and extending past the piston rod, a gear pivoted uponsaid bracket coincident with the fulcrurn of the lever and movable withthe lever, and operative connections between said gear and the pistonrod.

In testimony whereof I aiix my signature in presence of two witnesses.
